AMBROSE GOOSLIN, OF BLACKBERRY CREEK, KENTUCKY.

PIPE-GRAPPLE.

Specification of Letters Patent.

Patented has as, 1915.

Application filed July 10, 1914. Serial No. 850,160.

To all whom it may concern:

Be it known that I, AMBROSE Goosmn, a citizen of the United States, and a resident of Blackberry Creek, in the county of Pike and State of Kentucky, have invented certain new and useful Improvements in Pipe- Grapples, of which the following is a specification, reference being had to the accompanyingdrawings, forming a part of this specification.

This invention relatesto certain new and useful improvements in grapples, especially adapted to be used in removing pipe, casing and tile from wells, and my invention consistsin the novel features hereinafter described.

The primary object of myinvention is to provide a pipe grapple of a simple, durable and compact construction, which shall be capable of accurate and convenient manipulation in the removing of tubing and casings from wells.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views: Figure 1 shows a sectional view of a pipe showing my grapple arranged therein. Fig. 2 is an enlarged sectional detail of the grapple. Fig. 3 shows -a perspective detail of one of the spur bars.

Fig. 4 shows a sectional view through the carrying member showing a slight modification in connection with the means for securing the supportingring '14. Fig. 5 is a section on line 5, 5, of Fig.14. Fig. 6 is a section on line6, 6, of Fig. 4.

In my present invention I provide a pipe grapple arranged to be used in connection with difierent sizes of pipes or casing. The

construction is such that when the spur bars are spread to engage the maximum sizes of plpe creasing, the spur bars all have their ends resting against a solid structure so;

that there is no possibility of the carrying member collapsing under strain.

In the drawings the numerals 10, 1O represent two plates which are heldin parallel spaced relation and form the carrying member. At one end these plates are held in spaced relation by means of an intervening bar 11 and at the opposite ends by means of the intervening bar 12. As shown in Figs. 1 and 4, each plate 10 is provided with a neck extension 10. In Figs. 1 and 2 the two plate members are of one strip of metal provided intermediate of their ends with a loop 9 arranged to receive a ring 14. In Fig. 4, the plates 10, 10 are of separate sheets and instead of a loop 9 are provided with an opening 8 through which the ring 14 passes. At their upper ends the plates 10, 10 are securedto. the intervening bar 11 by means of the rivets a, and at their lower ends the intervening bar 12 is held in p0sition by means of the rivets 0.

Near their lower ends the plates 10 are provided with two oppositely positioned studs 9 which pivotally support the two spur bars 16, 16 each of which has its lower end u, chamfered or extending obliquely, so that these chamfered ends are stopped against the lower intervening bar 12, this bar 12 thus limiting the outward movement of the spur bars 16. Each spur bar has its upper end (Z pointed and near each upper end is provided with an opening 6, the points d being at the outer edge as clearly shown in Fig. 2.

In order to normally hold the spur bars 16 in their outwardly spread position and against the intervening stopbar 12, I provide the approximately U-shaped spring 13. which is of a width equal to the width of the spur bars 16 and is held between the two plates 10,10 in the manner shown in the drawings.

Secured to the outer face of each plate 10 is a channel iron 15, these channel irons being secured to the plates 10 by means of the rivets a, b and o, as clearly shown in Fig. 4.

Near its lower end each channel iron carries a stud 00, these studs being positioned in alinement with the studs 9 which support the spur bars 16. The studs 00 support the spur bars 18 which also have the points 07,

bases of the angle irons 15, as shown in Figs. 2 and 4:. The openings 2 containing the spring A are so arranged that the same come at a point immediately above the spring B, so that after once placing. the

spring A in position this spring will rest directly upon the spring B and hold the same in secure position between the plates 10, as will be understood in referring to Figs. 2 and l.

Secured to the upper ringlt is a suitable carrying strand F, while secured to each spur bar 16 and 18 is the lower end E of an operating strand D.

As shown in Figs. 4 and 2, the lower end of the carrying member is provided with a ring 13, to which is secured a member 20 extending from the weight 21. This weight isnecessary at times in order to insure the grapple properly descending within the pipe or duct. In lowering the grapple the same may be lowered by means-of the operating member D, so that the lower ends E will carry the weight of the grapple insuring the spur bars 16 and 18 being held against the carrying member. This insures the ready descent of the grapple. As soon as the member D is released and the grapple isheld by means of the member F, the spur bars are forced outward by means of the springs A and B. Then in raising the grapple by means of the strand F, the entire casing may be raised and lowered as the ends of the spur bars will positively engage the inner face of the casing.

When the spur bars are extended their full limit, the ends all rest against a solid structure as will be understood in referring to Figs. 2 and 4.

It is of course understood that grapples embodying my invention may be made in various sizes.

The grapple is simple and inexpensive in construction and both durable and eflicient in operation, and can be readily lowered within a tube or casing to positively engage the same.

Having thus described my said invention what I claim as new and desire to secure by United States Letters Patent is:

1. A device of the character described,

comprising a carrying member including two plates held in parallel spaced relation,
